How do I improve my Dinosmasher's Fury structural deck

Hello! I am a beginner duelist. I started on YGO not long ago, and bought the "Dinosmasher's Fury" structural deck. It comes with the following cards:

1x Petiteranodon

1x Ultimate Conductor Tyranno

1x Souleating Oviraptor

2x Megalosmasher X

2x Sabersaurus

1x Super Conductor Tyranno

1x Super-Ancient Dinobeast

1x Sauropod Brachion

1x Tyranno Infinity

1x Black Brachios

1x Miracle Jurassic Egg

1x Gilasaurus

1x Babycerasaurus

1x Miscellaneosaurus

1x Evilswarm Sallamandra

1x Stegocyber

1x Trifortressops

1x Skelesaurus

1x Chewbone

1x Rescue Rabbit

1x Lost World

1x Fossil Dig

1x Big Evolution Pill

1x Twin Twisters

1x Burial from a Different Dimension

1x Swords of Concealing Light

1x Painful Decision

1x Unexpected Dai

1x Terraforming

1x Survival's End

1x Survival of the Fittest

1x Fossil Escavation

1x Extincton on Schedule

1x Ojama Trio

1x Nightmare Archfiends

1x Quaking Mirror Force

1x Grand Horn of Heaven

1x Secret Blast

I would like to improve it. I've already thought about buying two more copies of "Lost World" and I've also thought about buying the following cards to build an extra deck: Transcendosaurus Exaraptor, Grenosaurus Giga-Cannon, Grenosaurus, Evolzar Dolkka and Evolzar Laggia.

I don't know if I'm on the right path.

I would like tips to improve the structural deck. It doesn't necessarily need to make it meta (because I don't even know if he has the capacity for that), but if it can become a little more competitive, I'm already satisfied. 

If you can, I ask for tips.
